I'd rather know what to expect … Work unpredictability as contemporary work stressor with detrimental implications for employees’ daily wellbeing

Figures & data

Table 1. Means, standard deviations, reliabilities, intraclass correlations and zero-order correlations on the day-level and the person-level.

1. Work unpredictability (at work)	2.50	1.07	.99	0.87	.76	.60		.25***	.26***	−.20***	−.08
2. Time pressure (at work)	2.79	0.95	.91	1.14	.75	.41	.54***		.15***	−.17***	−.05
3. Strain (after work)	2.27	0.70	.94	1.02	.84	.32	.49***	.46***		−.71***	−.46***
4. Serenity (after work)	4.98	0.86	.97	1.02	.86	.42	−.36***	−.30**	−.82***		.53***
5. Serenity (in the evening)	5.27	0.80	.98	0.90	.82	.44	−.48***	−.37***	−.83***	.97***

Notes: ICC, intraclass correlation coefficient; α, Cronbach’s alpha reliability estimates. Correlation coefficients above the diagonal are day-level (N = 666), below the diagonal are person-level correlations (N = 105). *** p < .001, ** p < .01 (two-tailed).
