If your application is received after this time limit, the tribunal will not usually accept it.If you are worried about how the time limits apply to you, take advice from one of the organisations listed underFurther help.Employment tribunals are less formal than some other courts, but it13、 is still a legal process and you will need to give evidence under an oath or affirmation.Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the organisations listed 14、underFurther help.If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your compensation if you win the case. This is known as adamages-based agreement. In England and Wales, your solicitor cant charge you more than 35% of 15、your compensation if you win the case.If you are thinking about signing up for a damages-based agreement, you should make sure youre clear about the terms of the agreement.

Twenty years of life trajectory deeply shallow, suddenly feel something, do it.一字開頭的年齡已經到了尾聲。或許是愧疚于自己似乎把轉瞬即逝的很多個不同的日子過成了同一天的樣子;或許是追溯過去,對自己那些近乎偏執21、的怪異信念的醒悟,這些天以來,思緒一直很凌亂,在腦海中不斷糾纏。總覺得自己自己似乎應該去做點什么,或者寫點什么。二十年的人生軌跡深深淺淺,突然就感覺到有些事情,非做不可了。The end of our life, and can meet many things really do?而窮盡我們的一生,又能遇到多少事情是真正地非做不可?During my childhood, think lucky money and new clothes are necessary for New Year, but as the advance of the age, will be more and m22、ore found that those things are optional; Junior high school, thought to have a crush on just means that the real growth, but over the past three years later, his writing of alumni in peace, suddenly found that isnt really grow up, it seems is not so important; Then in high school, think dont want t23、o give vent to out your inner voice can be in the high school children of the feelings in a period, but was eventually infarction when graduation party in the throat, later again stood on the pitch he has sweat profusely, looked at his thrown a basketball hoops, suddenly found himself has already ca24、nt remember his appearance.童年時,覺得壓歲錢和新衣服是過年必備,但是隨著年齡的推進,會越來越發現,那些東西根本就可有可無;初中時,以為要有一場暗戀才意味著真正的成長,但三年過去后,自己心平氣和的寫同學錄的時候,突然就發現是不是真正的成長了,好像并沒有那么重要了;然后到了高中,覺得非要吐露出自己的心聲才能為高中生涯里的懵懂情愫劃上一個句點,但畢業晚會的時候最終還是被梗塞在了咽喉,后來再次站在他曾經揮汗如雨的球場,看著他投過籃球的球框時,突然間發現自己已經想不起他的容顏。Originally, this world, can produce a chemical rea25、ction to an event, in addition to resolutely, have to do, and time.原來,這個世界上,對某個事件能產生化學反應的,除了非做不可的堅決,還有,時間。A persons time, your ideas are always special to clear.

Dislike his cowardice, finally found that there are a lot of love, there are a lot of miss, like shadow really have been doomed. Those who do, just green years oneself give oneself an arm injection, or is a self-righteous spiritual.一個人的時候,自己的想法總是特別地清晰。想要的,不想要的,界限明確,好像沒有什么可以撼動自己。也曾經好像已經下定27、了決心去做某件事,但更多的時候是最后又打起了退堂鼓。嫌惡過自己的怯懦,最終卻發現有很多緣分,有很多錯過,好像冥冥之中真的已經注定。那些曾經所謂的非做不可,只是青蔥年華里自己給自己注射的一支強心劑,或者說,是自以為是的精神寄托罷了。At the moment, the sky is dark, the air is fresh factor after just rained. Suddenly thought of blue plaid shirt; Those were broken into various shapes of stationery; From the corner at 28、the beginning of deep friendship; Have declared the end of the encounter that havent start planning. Those years, those days of do, finally, like youth, will end in our life.此刻,天空是陰暗的,空氣里有著剛下過雨之后的清新因子。突然想到那件藍格子襯衫;那些被折成各種各樣形狀的信紙;那段從街角深巷伊始的友誼;還有那場還沒有開始就宣告了終結的邂逅計劃那些年那些天的非做不可,終于和青春一樣,都將在我們的人生中謝幕。Baumgar29、tner the disappointing news: Mission aborted. r plays an important role in this mission.
