Think about your relationships with your colleagues… I bet there are at least some who you’d call “frenemies”. Maybe there’s a co-worker whose sense of humour you love, say — but who also irritates you by failing to pull their weight. In fact, the workplace is the ideal breeding ground for relationships that are characterised by simultaneous, strong positive and negative feelings — so-called “ambivalent relationships” (or frenemies) — note the authors of a new paper in the Journal of Applied Psychology.

It’s surprising, then, how little is known about how frenemies behave with each other, write Shimul Melwani at the University of North Carolina Chapel Hill and Naomi Rothman at Lehigh University. So the pair ran a series of studies to find out.

From ball pits to free beers, fun job perks have received plenty of press attention over the last few years. For millennials, such benefits should surely be appealing — they are, after all, the generation these perks were ostensibly designed for.

But according to a new study, young people themselves have a different priority in the workplace — respect. Writing in the International Journal of Business Communication, a team led by Danielle LaGree from Kansas State University finds that being valued and respected by managers was the key factor in employees’ ability to positively adapt to the workplace. And, in turn, this impacted how loyal workers were to their employers, how much they engaged in their work, and how happy they felt overall.

Having a “choice mindset” — believing, in short, that people’s behaviours are “choices”, or deliberate actions driven by their own motives and preferences — has multiple benefits. Those with a choice mindset feel as if they have control over their own destiny, for example, and see better outcomes in negotiations.

There are some drawbacks, however. Choice mindsets can lead to victim blaming, a lack of care about inequality, and a reduced interest in acts of social good. A new study in Social Psychological and Personality Science takes a closer look at these more troublesome impacts. Yidan Yin from UC San Diego and colleagues find that people in positions of power tend to adopt a choice mindset, which makes them more likely to blame others for mistakes.
