ive done plenty of projects over the years with various Managers and nothing changes ,If they need you your hired, if not no interaction.
its more of who you know to get hired nowadays, HR is unapproachable and submitting a general application/ resume is impossible.
Benefits have been cut back, but thats every where.
Hourly rates are good. Length of projects usually over a year in length
Decreased Benefit packages, Hard to get hired.your more of a number now.
