I might suggest you get out and get seniority elsewhere while you still have a chance and career time ahead of you.
Look at all that's happened and how people have responded selfishly in many senior cases. Allowing the divide and conquer and taking an 'it's all about me' position.
To be sure there are many who have NOT done this. But also many that have. As long as that happens things will get worse.
The past decades have seen an ever increasing chipping away at pay and benefits and worsening rostering. Not gonna get better unless management has an epiphany they will never have. They will have a mediocre not particularly productive work force with high costs to the company while individuals make less. Just the way it is.
With all the recent 'stuff' going on, how much ACTION have you seen ? If you're riding things out and staying, do what you need to do and be happy (and quit whining). The conditions you've seen are the conditions you'll get. Every day you spend here is wasted seniority elsewhere if you're looking at a long career in this business.
