As shown above, the NHLPA has filed a grievance on behalf of Jake Dotchin against the Tampa Bay Lightning for wrongful termination.
Dotchin is 24 years old, he was a 2012 6th round pick.
While this was a poor act by the defencemen who had not broken into the NHL on a full time basis yet, in my personal opinion it should not be a reason to terminate someones contract.
If someone shows up out of shape, he should be benched until he is at the point where he should be, or suspended by the team without pay not completely terminated.
But in a way, if you showed up to a normal job unable to do your duties you are most likely to be fired.
