I was let go from my job 2 weeks ago and the reason they gave was "without cause" i was there almost a year never been written up never even been given a verbal warning. Now I see they are hiring. Is this grounds for wrongful termination?

Unfortunately, your employer can terminate you at any time, for any reason, as long as that reason is not discriminatory and as long as they provide you with the appropriate severance. However, I do recommend reaching out to an employment lawyer at the number below in order to ensure that you have been provided with the appropriate amount of severance.
