I quit a job 3 weeks ago where I was promised a contract but wasn't given it when the time was there. Really regretted having to quit but I wasn't going to stay somewhere where I wasn't valued. (long long story not gonna bother you with it)
Today I landed a job with about 35% more pay, a fixed contract and better hours! As my title says, don't be afraid to take a leap and stand up for yourself! You can find something better
